Class 11 Computer Science

Introduction to Networking (नेटवर्किंग का परिचय)

Networking refers to the connection of computers and devices to share data, resources, and communicate effectively. It is the foundation of modern technology.
नेटवर्किंग का मतलब कंप्यूटर और डिवाइस को जोड़कर डेटा, संसाधन और प्रभावी संचार करना है। यह आधुनिक तकनीक की नींव है।

Advantages of Networking (नेटवर्किंग के लाभ)

• Resource Sharing: Share printers, files, and applications.
• Cost Efficiency: Reduces hardware and software expenses.
• Connectivity: Facilitates communication through email, video conferencing, etc.
• Centralized Management: Easier to manage data and resources from one location.

Components of a Network (नेटवर्क के घटक)

• Nodes: Devices like computers, printers, or servers.
• Communication Media: Cables (wired) or Wi-Fi (wireless).
• Networking Devices: Switches, routers, and hubs.
• Protocols: Rules governing data transfer (e.g., TCP/IP).

Types of Networking (नेटवर्किंग के प्रकार)

• LAN (Local Area Network): Covers a small geographic area like an office or home.
• WAN (Wide Area Network): Spans a large geographic area, such as the internet.
• MAN (Metropolitan Area Network): Covers a city or large campus.
• PAN (Personal Area Network): Small network for personal devices like Bluetooth or Wi-Fi.

Real-World Applications of Networking (नेटवर्किंग के वास्तविक अनुप्रयोग)

• Internet access
• Online banking
• Social media platforms
• Cloud computing
